MacBook Pro :: Left And Right Cursor Keys Not Working

Jun 21, 2012

My trusty four year old (2.33 GHz Intel Core 2 Duo) macbook pro has, all of a sudden, decided it doesn't want to let me use the left and right cursor keys any more. All the other keys work (including up and down) but the left and right ones don't, even when combined with modifier keys (e.g. Ctrl+<right> should but doesn't navigate across to a second pane in lion). Is it hardware or software problem. Seems odd from a hardware point of view that exactly 2 keys would fail simultaneously.

From a software point of view: I haven't installed anything new lately and I've closed down all the applications running on osx with no luck.†Is there some way I can diagnose whether this is hardware or software? Can I boot to a command prompt and test it there? does osx lion include an on-screen keyboard that shows each key being hit? I suppose I could install a keylogger but that might not be conclusive.

Running OS X 10.5.8 on a Macbook Pro that's roughly 2 years old (maybe a little more). About a week ago I noticed that I was unable to copy/paste/undo/cut. Thought it was a total command key failure at first but other shortcut functionality is intact (cmd+t/cmd+w etc). So I've isolated the problem to the left cmd key and the bottom row of my keyboard. Separately they work just fine, but they refuse to work together.

I'm trying to use iphoto but when I put my cursor over a photo it has a small flag in the upper left hand corner and a downward arrow in the lower right corner.I've used it lots but it just started doing this. My events pull up just not a single photo.

I got a 13" MBP09, my first mac, a couple of days back. The experience has so far been exemplary, but there are few PC stuff I'm used to, like the End/Home/Pg.Up/Pg.Dn functionality, Shift+Arrow keys to select, really useful while working on Word Processing apps. What are the Mac equivalents of these? Also, how do I increase the speed at which the cursor moves across a line? It's really slow.

I'm using the thin aluminum USB external keyboard and suddenly my 8ik, diagonal of keys stopped working (now I'm using my laptop keyboard). Anyone know if this is typically a sign of a broken keyboard, or a user issue?

I am having problems with my cursor on my macbook.¬†Since a recent software¬† update I've not been able to move the cursor in any app. The¬† only way it moves is when I type. I use the arrow-keys to quickly move around menus but that is impossible. I have looked at all the settings I can think of looking at, but nothing makes any difference.¬†Helen¬†BTW the OS is 10.6.8

F3 and my right shift key have suddenly become play/pause keys in addition to their original functions. My F8 doesn't really do anything anymore and does not even light up in Keyboard View. I've tried to use Sizzling Keys, and reset Keyboard Shortcuts but the problem still persists. It seems to affect most music playing programs (iTunes and Vox. I have a Macbook Model 5,2 and Mac OS X 10.5.8

I recently spilled a protein shake over my mb pro. It spilled on the right side, but I quickly cleaned it with a wet tissue and dried it up. The problem, now, is that the illuminated keyboard isn't working..only a few random keys are working and the rest aren't..

What should I do? I have a 1 year warranty left, but I'm not sure it'll be covered.

So I've got a 2006 MacBook Pro that's worked fine for me since the day I got it...until now.

The left fan has stopped working so now the left side of the laptop is considerably hotter than the right. I'm from the UK and so is the laptop but I'm traveling around the US at the moment so I was just gonna take it into the next Apple Store I come across.

Also, if I do take it in, what are the chances they'd charge me to fix it? My applecare expired, typically, about 2 months ago.

I reinstalled OS X from a Leopard dvd earlier (took it to an apple store and borrowed their superdrive), then transferred my info from my black macbook (latest revision, so has the volume keys as F10,F11,F12, play at F8 etc) via time machine. Once that had finished, I logged in on the air and tried to lower the brightness. It wouldn't work, so i tried the other F keys and they don't perform their functions.

had my macbook for about a year and a half and recently it just stopped working. Literally it was fine one minute and the next the screen was just black. I tried turning it on and off and now it stays at the boot screen for like 30 minutes and then just goes to a blue screen. I can move the cursor around the blue screen and stuff but there are no icons and there is no finder or anything. everytime i turn it off and back on the same thing, bootscreen and then bluescreen.

Yesterday, without spilling anything on it, the left click on my trackpad (and on my wireless mouse) stopped functioning(MacBook Air/OSX 10.6.4/1.6 GhZ) After one hour it started working again. At first, I thought it must be related to settings that i had messed up in the meantime (Universal access, mouse keys etc).However it turned out not to be the case. I tried virus scan, PRAM reset, but it didn't help. Today i took it to the Apple store, they proposed to replace the keyboard. Since I am out of warranty I don't want to pay 200 euros if the problem can be solved without the replacement of the keyboard.

Searched and kind of found an answer, but it doesn't seem to be 100% correct for me. Right now, MOST of the FKEYS do what is printed on them, controlling sound, brightness, F9 and F10 only work when you hold the fn key (lower left). How can I get those to work without that? I know there is an option in the Keyboard control panel, but that only makes it so I have to use the fn key for ALL of them.

The LEFT and DOWN directional arrows on my Mother's MBP just stopped working. All other keys work fine. Does this generally mean I will need to replace the top case? Has anyone out there experienced keys not working, then working again? Could it possibly be the connection to the logic board? Or some dust in an undesired location?

My cat slept on my MacBook last night and now the keyboard isn't working properly ... Some keys don't do anything at all and some keys do things they shouldn't... Any clues on how to fix this? I called the apple support line and we don't think it was anything to do with the settings in 'universal settings'. I'm not sure what else to do and this is one time I do wish I had a man in the house?! Or at least someone else who has half a clue! I rely haven't had many problems with my MacBook 'till now. I'm operating on Mac os x 10.6.8¬†Also, 2 cats free to good home. Or anyhome, it doesn't even need to be 'good'! ¬†

I have a Macbook Air and I just recently realized that some of my keys do not work or they will work when I press the letter or number next to the key that I need. I do not know what is wrong or why this is doing this since I got the computer on March 26, 2012.

I am trying to use all my F Keys, volume up/down, turning up the light on screen as well as the keys, and nothing is working. I just bought this Mac 2 days ago. Is there something I need to do? Or is a malfunction?

Yesterday i was using my Mac Book, it was working fine, but today as i turned on my Mac Book, i tried to enter my password there, it was not accepting my password. the 5 keys which are not working on my machine are "QWERU" , what could be the reason that they keys are not working?

One of the keys on my keyboard are not working. The letter "b" isn't working for me.(I had to copy+paste the letter.) Is there any solution? I restarted my computer and even followed to apple instructions in hopes that it would work. However, the key still doesn't work.

I have owned my MacBook Pro for about 3 years and just a couple of weeks ago the trackpad stopped working when I clicked on it. I can still use it by finger touch but I can no longer left or right click on it. I have been using a mouse for the past week so that I can right click.

I am not sure what happened but it seems my two year old child might have spilled something on my macbook. The keyboard stopped working and when I pressed a key the letter "Z" got stuck. I purchased a used "topcase" from ebay, installed it and I am still experiencing the same phenomonon, although other letters can type normally. My gut instinct is that there is something else wrong ""deeper to the keyboard".

The 'Return' and 'Backspace' keys on my mac have recently stopped working. Nothing was spilled on them and nothing seems to be wrong with them when pressed down. I also removed the keys and checked that there was nothing in the way, but there wasn't. I have rung apple and they said it would need to be taken into a store, but there isn't one near by and it will be a few weeks until i can take it in. In the meantime, is there any way that I could remap the keys in question to another couple of keys. For instance right command and right option?
